Hi Carl. I'm not sure if i've got your question. But if you are checking the possibilities for connecting to XTRA4210N with rs485, the answer is yet. you can use the cable/bluetooth/wifi module to get connected to it.

Please feel free to visit our official website, on the right bottom corner, there is an chat button, feel free to ask all your questions there, have a nice day!

Please check with your seller for your requests, thanks in advance and have a wonderful day!

Answer 1: Yes, you can control your controller via WiFi, but not remotely, if you are familiar with solar DIY, we have released the STA mode for WiFi, you can find out how to connect remotely by yourself, due to that each country internet provider and ports are not same, so we can not provide any instructions. Answer 2: For iTracer series, you can not charge any Lihitum battery. Answer 3: MPPT controller track the max power point automatically, so there isn't a best voltage point that you can set manually. Answer 4: The internal button battery is for powering the storage core, so that the controller can collect data.

Hi, please drop an email to helpdesk@epever.com, we will have technicians help you out.

Hello Sir, We don't suggest to use 2 PCS charge controller to charge one lithium battery bank. It may cause the BMS protection.

Hi Sir, thanks for reaching out. Usually the MT50 connects with the controller, so it's no necessary to put the battery bank on it.

Please go to our official website, under CONTACT, you can find the sales information, feel free to contact them, thanks in advance!

Hi Molo75. If you connect to the load, the voltage of the battery will be pulled down, so the SOC will become smaller.If the change is relatively large, there are two possibilities: the load power is relatively large, or the battery capacity is too small. You can also email support@epever.com for more help.

Hi Sir, Thanks for your question. Could you please describe more details about your question? What's the type of your battery? Do you mean whether that battery can match the mppt charge controller?

@@Epever Thank you very much. I own a 40-amp charging regulator and a 200-amp long ATM battery, and you have four 150-watt panels. Does your charging regulator accept me as a guest of two 150-watt panels next to the 4 150-watt panels? Here is the question.

@@Epever Thank you for your reply. I just want to ask. I own the charging regulator of a company of 40 amps and the connector of the panels respectively. I have four panels of the type 150 watts. The question here is can I add two panels of 150 watts from the previous four in Facebook, the 6 panels in a series system, will the regulator be affected? You have a negative or it will be a normal battery type Long EGG M 200 amp.

Please i need help

Hi Mihai, thanks for reaching. Did your product break during the upgrade, or did it break before the upgrade? Could you please describe more details?

has break during the upgrade , but i repeated the procedure and succeeded in the third attempt now the display shows me n7 for lithium-ion 7S but in the application on the pc it does not display the values ( parameters )

@@qzz9102 You can use them, but they should be in the places with uni-directional current flow. A polar DC breaker on the charge controller side of the bus-bar and another one on the inverter side of the bus-bar will work. It would then take throwing two switches to isolate the battery bank but it's a more flexible design since you would be able to disconnect the charge controller and still leave the batteries powering the inverter or, conversely, disconnect the inverter and still leave the charge controller charging the batteries. You could also disconnect the entire system by throwing both breakers which is extremely useful in maintenance and debugging. The polar nature of a breaker is not a problem in these two locations since there is uni-directional current flow there --- the charge controller battery terminals do not sink DC current and the inverter battery terminals do not source current.

@@Enel8888 Yes. If you put the breaker in the location where this video has it, you should make sure the breaker is non-polar.

Hi Ahmad, thanks for your suggestions. Welcome and let us know if you have any other suggestions, thanks again.

Hi Sir, thanks for your question. Normally you can directly connect the load on the inverter when you use inverter in your solar system.

Thanks for your suggestions ,Master T.
